Floating Spa Blanket
- Bubble Covers
- Ctn of 10 pieces
- Heavy-duty floating blankets (aka thermal blankets) are made of a 1/4" thick, 2 Lb.
density, closed cell, cross linked polyethylene foam.
Foam is 'closed cell' it won't absorb water, and
unlike other thermal blankets it isn't necessary to coat the foam with a colored vinyl to
keep the water out.
The advantages of a simple floating blanket are rather amazing.
The most important thing a floating blanket does is to almost completely eliminate evaporation. By eliminating the evaporation a floating cover can reduce the operating costs of a spa in numerous ways.
